To use features like *circular scrolling*[^1] of a Synaptics touchpad, you need to add the following lines to
|
||
|
|
your `/etc/X11/xorg.conf`:
|
||
|
|
|
||
|
|
~~~
|
||
|
|
Section "InputDevice"
|
||
|
|
Identifier "Synaptics Touchpad"
|
||
|
|
Driver "synaptics"
|
||
|
|
Option "SHMConfig" "true"
|
||
|
|
Option "SendCoreEvents" "true"
|
||
|
|
Option "Device" "/dev/psaux"
|
||
|
|
Option "Protocol" "auto-dev"
|
||
|
|
Option "HorizEdgeScroll" "0"
|
||
|
|
EndSection
|
||
|
|
~~~
|
||
|
|
|
||
|
|
You also need to add the following line into your `ServerLayout` section in that file:
|
||
|
|
|
||
|
|
InputDevice "Synaptics Touchpad"
|
||
|
|
|
||
|
|
<p><div class="noteclassic">
|
||
|
|
After an upgrade to Jaunty, these lines are commented out by the update-manager. Just uncomment them and everything
|
||
|
|
should work again.
|
||
|
|
</div></p>
|
||
|
|
|
||
|
|
Afterwards you can install the [gsynaptics](apt://gsynaptics) package to manage the settings for your touchpad - incl.
|
||
|
|
enabling the circular scrolling.
|
||
|
|
|
||
|
|
|
||
|
|
[^1]: It's like a jogdial: just draw a circle with your finger starting from top-center. Clockwise will scroll down, counter-clockwise will scroll up.
